BACKGROUND OF THE INVENTION

[0002] In the prior art, a conventional gaseous fuel generator provides an electric power controller to control an electrolytic cell, which can electrolyze water into a mixed gas of hydrogen and oxygen. A valve is provided to control the flow of the mixed gas and sent it to a burner. The burner is to burn the mixed gas and the electric power controller is to provide the essential power for the electrolytic cell to electrolyze water. In operating, operator first has to start the electric power controller to drive the electrolytic cell to generate the mixed gas of hydrogen and oxygen. Then, operator must control both of the electric power controller and the valve to have predetermined rate of the mixed gas sending to the burner. But the factors of affecting the electrolytic reaction are very complex, such as temperature, precipitation of reaction and the efficiency of electrolyzing etc. The operator is hardly to control an equal quantity and a steady rate of generating the mixed gas in every moment of the period of burning.

DETAIL DESCRIPTION OF THE INVENTION

[0010] Please refer to FIG. 1, a gaseous fuel generator of the first prefer embodiment of the present invention comprises a controller 10, a gas generating assembly 20, a tube 30, an adjusting valve 40, a pressure sensor 50 and a burner 60, wherein.

[0011] The controller 10 is an electric power controller 11 in the present embodiment, which provides essential electric power to the gas generating assembly 20.

[0012] The gas generating assembly 20 has an electrolytic cell 21 and two electric poles 221 in the electrolytic cell 21. The gas generating assembly 20 is to electrolyze water into mixed gas of hydrogen and oxygen and transports the mixed gas by the tube 30. The quantity and rate of generating the mixed gas depends on the direct current provided from the controller 10.

[0013] The adjusting valve 40 is to control the flow of the mixed gas in the tube 30.

[0014] The pressure sensor 50 is to detect the pressure of the mixed gas in the tube 30. The detected data is comparing to the last time's detected data to be converted to an electric signal feedback to the electric power controller 11 of the controller 10. The electric power controller 11 can adjust the current of the electric power supplied to the electrolytic cell 20 according to the signal provided by the pressure sensor 50. Thus, the quantity and the rate of generating the mixed gas of hydrogen and oxygen in the electrolytic cell 20 can be controlled automatically and precisely in a steady status. The pressure sensor 50 can be an electronic sensor or a mechanic sensor.

[0015] The burner 60 can be a welding device, a heater, a motor-driven device of the stove, a baker or a heating stove etc. to communicate with the tube 30 to get the mixed gas of hydrogen and oxygen. The burner 60 has a one-way valve 61 between the inlet of the burner 60 and the tube 30 to prevent the mixed gas flowing back to the tube 30.

[0016] The gaseous fuel generator of the present invention can precisely control the quantity and the rate of generating the mixed gas of hydrogen and oxygen by means of the pressure sensor 50 can provide electric signals of voltage or resistant according to the variation of the pressure of the mixed gas in the tube 30. These signals are sent to the electric power controller 11 to make the electric power controller 11 to adjust the current of electric power supplied to the electrolytic cell 20. In the other words, if the pressure in the tube 30 is set to 1 atm but the value detected by the pressure sensor 50 is 0.9 atm, the electric power controller will increase the current of electric power ssupplied to the electrolytic cell 20 to make the electrolytic cell 20 can generate the mixed gas in a higher rate. That will make supplying rate of the mixed gas of the gaseous fuel generator keeping steady and make the burner 60 to have a steady burning status to reduce the precipitation of the electrolytic reaction, the aging of the electric poles and the variation of the temperature.

[0017]FIG. 2 shows a gaseous fuel generator of the second prefer embodiment of the present invention, which is similar to the first prefer embodiment, except that further has a mixing chamber 22 disposed in a gas generating assembly 20, which has hydrocarbon solution 221 and hydrocarbon gas 222 (formed from evaporating the solution 221) therein. A tube communicate the electrolytic cell 21 with the mixing chamber 22 and has the end opening in the hydrocarbon solution 221 to increase the rate of evaporating the solution 221 to the gas 222. The controller 10 has an electric power controller 11 and a pump 12 for pumping air, which has ⅕ oxygen component, from outside to the hydrocarbon solution 221 in the mixing chamber 22 to increase the rate of evaporating the solution 221 to the gas 222. The rate of the hydrocarbon solution 221 evaporated to gas 222 is according to the quantity of the pump 12 pumping air to the mixing chamber 22. More air is pumped to the mixing chamber 22 will make a higher rate of the hydrocarbon solution 221 being evaporated to gas 222. On the contrary, less air is pumped to the mixing chamber 22 will make a lower rate of the hydrocarbon solution 221 being evaporated to gas 222. A pressure sensor 50 is to detect the pressure in the tube 30 and send a signal to the electric power controller 11.

[0018]FIG. 3 shows a gaseous fuel generator of the third prefer embodiment of the present invention, which is similar to the second prefer embodiment, except that the pressure sensor 50 sends the signals to the pump 12 to change the quantity of air pumped to the mixing chamber 22 for balance the request and the supply of the mixed gas.

[0019]FIG. 4 shows a gaseous fuel generator of the fourth prefer embodiment of the present invention, which is similar to the second prefer embodiment, except that the pressure sensor 50 sends the signals to both of the electric power controller 11 and the pump 12 to change the generating rate of the mixed gas of hydrogen and the oxygen and the evaporating rate of the hydrocarbon solution 221 both.

[0020] In brief, the present invention provides the pressure sensor 50 to detect the gas pressure in the tube 30 for providing a signal feedback to the controller 10 for precisely controlling the supplying rate of the mixed gas of hydrogen and oxygen of the gaseous fuel generator of the present invention keeping steady.

[0021] It is to be noted that the aforesaid embodiment of the present invention uses the pressure sensor 50 as a detector of the feedback control system. However, a temperature sensor can be used in stead of the temperature sensor to detect the temperature of the gas generating assembly 20 for providing a signal feedback to the controller 10 for controlling the supplying rate of the gaseous fuel generator. In addition, the pressure sensor and the temperature sensor can also be used simultaneously for precise controlling.
